Color object over Black and White

Trying to grasp the idea of a color object in a black and white video.
Example: I have a video of someone eating a red apple. I'd like to make the entire video Black and White, but keeping the Apple red. Any Hints, ideas or tips ??

That's the topic of my next newsletter which I hope to send out next week! What's your e-mail address?

A number of approaches can be taken, but the one that's generally most effective is:

Copy the video onto two tracks.
Make the lower track black and white.
Generate a mask out of the upper track, using the color wheels to leave you with only the desired color.

is the masking of the object going to move up down and twirl around with the moving image?
or isnt the masking stationary (only masking one area thoughout the video) ?

I sent the article and the mask will follow the object.

This has been discussed several times. The solutions suggested generally involve using the secondary color corrector. Here are some links:

There are 3 veg files that teach this on the Sundance site. Joe Sacher did a very nice 'demo' veg as well, to teach how to do this. There is also a tutorial in my book on Vegas, plus an article on the DMN.
